Aw, mama, you're so close na! Honestly, a few of us tried walking around the mall or doing gentle squats, and some swear na pag nag-eat ng spicy food or pag intimate with partner, it helped move things along, pero walang guaranteed remedy talaga, kaya best to check with your OB kung ano ang safest for your situation. At this point, I'd really recommend having a chat with your doctor about what you can safely do, especially since you're already at 39 weeks, para makasiguro na okay lang lahat ng ginagawa mo. Hang in there, mama, baby will come soon!
